It was suggested by Bill Mitchell during dinner at one of our SNNS evenings that like-colours tend to attract. The concept was interesting, that seemingly random acts of colour are somehow attracted to one another ... a cluster of parked red cars and another red car pulls in, a woman in red walks into an already predominately red scene, a number of black cars gathered at the back of a parking lot ... random acts, or perhaps these are not quite as random as we believe!
